| Description |
The Kovaya Limestone Mine is situated on the Saurashtra coast of India. Though the mine is dependent on the desalination plant installed in the plant for its domestic and industrial water requirements, there is significant withdrawal of groundwater by the large number of bore wells
and open wells, which are present in the agricultural
fields lying in and around the leased area of the mine. The heavy withdrawal of groundwater has led to intrusion of seawater. The present work entails study of possible seawater intrusion by chemical analysis of major cations and anions in selected groundwater samples. Very high total
dissolved solids in the range of >1,000 mg/l and high chloride in the range of 103 mg/l to 3,899 mg/l have been measured in the groundwater samples. ‘Resistivity Imaging Survey’ has also been carried out on selected profiles in the study area. The Electrical Resistivity Tomography images indicate very low resistivity zones (∼0–3 � m) in the
bottom portion of the resistivity depth section
